Overview:

The PPE Front Differential Cover is a robust upgrade designed specifically for the Jeep Wrangler models from 2018 through 2025. Engineered to replace the factory stamped steel cover on the Dana 30-M186 front differential, this heavy-duty cover offers enhanced protection and durability for serious off-road enthusiasts. Whether you’re tackling rocky trails, mud, or uneven terrain, this cover provides the strength and reliability needed to safeguard your differential against impacts and harsh conditions.

Ideal for Jeep owners looking to improve their vehicle’s durability without compromising approach and departure angles, the PPE front differential cover is a bolt-on solution that combines rugged construction with thoughtful engineering. It is built to withstand the torsional stresses encountered during off-road driving, ensuring your differential remains secure and functional under demanding conditions.

Key Features:

This front differential cover incorporates several advanced features to enhance performance and durability:

• Constructed from thick, high-strength nodular iron for maximum impact resistance
• Transverse gussets provide additional rigidity and strength to the differential housing
• Recessed hardware design protects bolts from damage during off-road use
• High and low fluid check ports accommodate pinion angle changes from vehicle lifts
• Service plugs equipped with high-temperature-rated neodymium magnets to capture ferrous metal particles and protect differential fluid
• Optimized shape to maintain or improve vehicle approach and departure angles
• Direct bolt-on installation with no modifications required
• OEM part number reference: Mopar 68391563AB for compatibility assurance

Construction & Design:

The PPE front differential cover is crafted from premium nodular iron, a material known for its superior strength and durability compared to standard stamped steel covers. This cast construction provides a thick, solid barrier that resists dents, cracks, and deformation from trail hazards. The inclusion of transverse gussets reinforces the housing, reducing flex and improving the overall structural integrity of the differential assembly.

Special attention has been given to the cover’s design to ensure it does not interfere with the Jeep Wrangler’s off-road capabilities. The shape is engineered to optimize clearance, helping maintain critical approach and departure angles. Additionally, the hardware is recessed within the flange, minimizing exposure to potential damage from rocks or debris.

Installation & Fitment:

Installation of the PPE front differential cover is straightforward and designed as a direct bolt-on replacement for the factory cover on Jeep Wrangler models from 2018 to 2025 equipped with the Dana 30-M186 front differential. No welding, cutting, or modifications are necessary, making it an accessible upgrade for both professional installers and experienced DIY enthusiasts. It is recommended to verify part compatibility prior to purchase to ensure a perfect fit.
